allaun 7518de6849 feat: goormaghtigh_finite_search now proven via native_decide on nested quantifiers
Key change: goormaghtigh_finite_search is no longer an axiom. Replaced
with native_decide proof using nested ∀ x ∈ Icc, ∀ m ∈ Icc, ... which
is fast (avoids constructing a 958K-element Finset).

Also added:
- repunit_mod_pred lemma: R(x,m) ≡ m (mod x-1)
- goormaghtigh_collision_mod lemma: cross-residue sieve
- Theorem now includes 4 ordered forms (adding (2,5,5,3) and
  (2,13,90,3) for completeness)

Only goormaghtigh_boundedness remains as axiom.
